Subject: Request letter for organising excursion.

Sir,

The School is planning a week long trip to Shimla for the students of classes X to Xll during their summer vacations. A group of 40 students along with 3 teachers will be visiting Shimla.

The touring party intends to leave chandigarh on 7'August 2020 and return on 13' August 2020 You are requested to arrange Volvo bus for ferrying the students to end fro and local sight seeing trips. Kindly book 15 rooms on a triple sharing basis in a 3 star hotel, Close to the Mali road. The rooms should have E good view and 24 hours hot and cold water.

In such cases arrangements can be made kindly confirm at the earliest. Also send us a list of estimated expenses.

Your's Sincerely,

ABC

The chemical reaction involved in the electrolysis of water is

From the above reaction it is clear that the amount of hydrogen gas and the oxygen gas formed are always in the ratio of 2:1. Therefore the volume of gas collected in the first test tube is double the volume of the gas collected in second test tube.

Since pressure in the veins is normally relatively low, for blood to flow back into the heart, the pressure in the atria during atrial diastole must be even lower.So this means that veins have blood pressure.

Blood flows in the same direction as the decreasing pressure gradient: arteries to capillaries to veins. ... As vessel diameter decreases, the resistance increases and blood flow decreases. Very little pressure remains by the time blood leaves the capillaries and enters the venules.

Let the numbers be a - d, a, a + d which are in AP.

(a - d) + (a) + (a + d) = 27 .........(1)

(a - d)(a)(a + d) = 405 ..........(2)

(1) => 3a = 27

a = 9

(2) => (a2 - d2)(a) = 405

[(9)2 - d2] (9) = 405

(81 - d2) (9) = 405

729 - 9d2 = 405

9d2 = 729 - 405

9d2 = 324

d2 = 36

d = 6

Now, substitute the values in the 1st equation.

(a-d) = 9 - 6 = 3

a = 9

(a+d) = 9 + 6 = 15

Hence the numbers are 3, 9 and 15.

Lateral Displacement is the perpendicular distance between the emergent ray from a glass slab and the incident ray produced forward.

When the perpendicular distance between the original path traced by an incident ray and the path traced by the emergent ray coming out from the glass slab is known as lateral displacement.

Following are the factors on which lateral displacement depends:

• The thickness of the glass slab
• Refractive index of the glass slab
• The angle at which incident ray enters the glass slab

• Digestion of food in our body is a decomposition reaction.
• Decomposition reaction is a type of chemical reaction in which single compound splits into two or more simple substances.
• In digestion of food carbohdratess, proteins, fats dcomposes to simple substaces that provide energy to do work.

3x+2y=11

2x+3y=4

by adding them

5x+5y=15

x+y=3

x=3-y

put the value of x

3x+2y=11

3(3-y)+2y=11

9-3y+2y=11

9-y=11

-y=11-9

-y=2

y=-2

put the value of y

x=3-y

x=3-(-2)

x=3+2

x=5

hence x=5 and y=-2

In a democracy, the three organs of the government namely executive, legislature and judiciary perform different functions. The powers of all the three organs are separated so that no organ becomes too powerful and is able to keep a check on the other organs. For example, even though ministers and government officials exercise power, they are held responsible to the Parliament or the State Assemblies. Likewise, although judges are appointed by the executive branch of the government, they have the authority to check the functioning of the executive or legislations passed by the legislature. This arrangement is called the system of checks and balances.

A strong base is a base that is 100% ionized in solution. If it is less than 100% ionized in solution, it is a weak base.

x + y = a + b …(i)

ax – by = a² – b²…(ii)

To solve these equations, we need to make one of the variables (in both the equations) have same coefficient.

Lets multiply equation (i) by b, so that variable y in both the equations have same coefficient.

Recalling equations (i) & (ii),

x + y = a + b [×b

ax – by = a² – b²

⇒ bx + ax = ab + a²

⇒ (b + a)x = a(b + a)

⇒ x = a

Substitute x = a in equations (i)/(ii), as per convenience of solving.

Thus, substituting in equation (i), we get

a + y = a + b

⇒ y = b

Hence, we have x = a and y = b.

Right to Be Informed: A consumer has the right to have correct information about a product. There are rules which make it mandatory to mention ingredients and safety features on the pack of a product. Proper information helps a consumer to make informed buying decision. A pack of a product also needs to mention the MRP (Maximum Retail Price) and a consumer can complain if the seller asks for more than the MRP.

Right to Choose: A consumer has the right to choose from different options. A seller cannot just offer to sell only one brand to the consumer. The seller has to offer various options to the consumer. This right is usually enforced through laws against monopoly trade.

Right to Seek Redressal: If a consumer gets affected by false promises made by the producer or suffers because of manufacturing defect; he has the right to seek redressal. Suppose you took a mobile connection and the bill shows many hidden charges which were not explained to you earlier. Or the mobile company activated a ringtone without your permission. Then you can go to the consumer court to put your case.

Consumer Protection Act 1986, a major step taken in 1986 by the Indian government was the enactment of the consumer protection act popularly known as COPRA.

1) It applies to all goods and services .

2) It covers all sectors that is private public and cooperative .

3) It gives rise to consumers . Established Consumer Protection councils at centre and state levels .

Under COPRA , three tier quasi-judicial machinery at district, state and national levels was set up for redressal of consumer disputes . The act has enabled the consumers to have the right to represent in the consumer courts the enactment of COPRA has led to the setting up of separate departments of consumer affairs in Central and state governments .

The rationale behind the enactment of Consumer Protection Act (COPRA) 1986 was to set up separate departments of Consumer Affairs in central and state governments to safeguard the interests of the consumers and to grant them the right to seek redressal against unfair trade practices and exploitation.

The capacity to do work is termed as Energy. The Energy expended to do work in unit time is termed as Power. It is represented as P.
Power Formula is articulated as,

P= E/t

P = W/t

or,

Where,
The Energy Consumed to do work = E
Work done = W 
Time taken= t 

The cause of the Silesian weaver's uprising was the cheating of the weavers by the contractors. In 1845, the weavers raised a revolt against the contractors who used to supply them raw material to weave textiles in finished form. The contractors drastically reduced their payments. The viewpoint of the journalist Wilhelm Wolft for this uprising was as fellows- Weaver's crowd reached the house of the contractor and demanded higher wages. They were not treated well, so a group of the crowd entered the contractors house forcibly and destroyed the furniture, window panes, plundered it. This shows that the viewpoint of the journalist was biased against the weavers and in favour of the contractor. On the other hand, the journalist did not understand the root cause of the uprising. He did not understand the poverty of weavers.
